Is Sapia much different from Nova Mondai?

The primary difference is that its size is twice as large and the atmospheric composition is different. You'll be at a lower technological level, say WW1, but I'll permit relatively massive nations to compensate. Also, while it may be habitable temperature-wise, Nova Mondial-native races would have to wear gas masks or some kind of apparatus to be able to breathe outside lest their respiratory systems suffer.

But realistically, you'll have to know that you'll be a subject of colonization. While you may be able to field much larger forces than the colonizers, it's uncertain how powerful things like machine guns and conventional artillery could be against laser satellites and and railgun tanks, among other things, as well as sort out whatever internal conflicts you may have had with your neighbors as the colonizers arrive. That being said, there will be fewer nations present, so you'll likely have less of those. It's an interesting situation with a lot of story potential, if you're prepared for it.
